= Technical Information
|
|
|
|
Here is the information that we have or suppose about the different components of the system.
|
|
|
|
== Chassi
|
|
The chassi of the VMC is a CC-VPX3-06-99.
|
|
VPX stands for Virtual Path Cross-Connect and is a set of standards for connecting components, apparently common for products from defense contractors.
|
|
VPX seems to be both a hardware format standard and a communication standard.
|
|
The chassi is a VPX chassi as it offers to connect VPX-compatible boards.
|
|
It also provides power to the boards --- although it is still unclear how precisely.
|
|
|
|
#text(fill:red)[Q: It would be helpful to get a schematic or a photo of how the boards are installed in the chassi, and how they receive power.]
|
|
|
|
== 68PPC2 SBC
|
|
The board in the first slot of the chassi is a 68PPC2.
|
|
This board is connected to the Mission Computer (via the Comm. Converter Board).
|
|
It is unclear if this board processes some data or if it is only responsible for communication.
|
|
|
|
#text(fill:red)[Q: Info about the role of this card would be helpful in identifying the points of interest.]
|
|
|
|
== 68G5
|
|
The second board, installed in slot 3, is a 68G5.
|
|
The role of this board needs to be clarified. It is connected to the Software Control Module (SCM) but the role of both these components is unclear.
